SPECIFICATION forming'part of Letters Patent No. 729,381, dated May 26, 903.

Application filed January 14, 1903. Serial No. 138,948. (No model.)

To a. whom it may concern.-

Be it known that we, ALBERT F. MOHN and PETER M. F-ELTWELL, citizens of the United States of America, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and usef ul Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in horseshoes; and the primary object of the invention is to construct a shoe with removable calks and toe, which may be readily placed in position and removed therefrom within a short space of time.

A further object of the'invention is to construct a shoe which when attached to the hoof of the horse may be left attached thereto until the body of the shoe becomes worn to such an extent as to requirea new shoe, and when so attached to the hoof the calks and toe of desired form may be readily renewed in the shoe.

It is a further object of the invention to construct a shoe of this character whereby sharpened calks and toes for use on icy streets or highways may be readily attached to the shoe and when it is not desired to use the shoe with the sharpened calks and toes the'same can be readily removed and calks'and toes of other approved form substituted for the sharpened ones.

The above broadly embody the objects of the invention, and briefly described the invention comprises a'horseshoe of the usual shape or contour which is provided at the toe with a pair of openings, preferably having tapered walls, these openings being adapted to receive correspondinglyshaped shanks carried on the toe-piece. This toe-piece may be sharpened or it maybe-of the form'adapted for use on dry streets 'or highways. The shoe at the heel e'nd'is further provided with openings, preferably having tapered walls,

' calksand the toes are fastened in position by set-screws which pass into the shoe at an incline to the horizontal line, and the ends of the said screws engage in seats provided therefor in the shanks of the calks and toes. The inclining of the fastening means serves to draw the shanks ofthe calks and toes firmly into the openings as the fastening means is tightened, and therefore serves to the better securing of the calks and toes, as any strain against the screws will not be so liable to bend the same.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification,and wherein like numerals of reference indicate like parts throughout the several viewsfin which Figure 1 is a detail perspective view of our improved horseshoe, the toe and one of the calks being shownin position and the other calk removed. Fig. 2 is a transverse section through the body of the shoe and toe with the toe-piece removed. Fig. 3 is a transverse section through the body of the shoe at the heel end with the calk removed. Fig. 4 is a like View of the shoe, showing the fastening means extending on a straight line. Fig. 5 is a detached detail perspective view of the sharpened toe-piece. Fig. 6 is a like View of one of the'heel-calks. Fig. 7 is a like View of the toe-piece which may beused for ordinary driving. Fig. 8 is a like View of the heel-piece of similar form of construction.

In the accompanying drawings, 1 indicates [the shoe proper, which is provided with the usual nail-holes 2 and is of substantially the ordinary form of shoe. Adjacent to the rear or calk ends of the shoe the latter is provided with openings 3, the walls of which are preferably tapering, the larger end of the opening being on the underneath face of the shoe. The shoe is also provided at the toe end with a pair of similar openings 4:", placed in line across the. toe some distance apart. In the openings in the toe of the shoe are fitted the tapered shanks 5 of the toepiect, which may be of the form shown in Figs. 1 and set the drawings, or where itis not desired to use the sharpened toe-piece it may be of the ordinary rectangular form, as seen at '7 in Fig. 7 of the drawings. Either form of toe-piece employs the same form of shank, and consequently the same reference-numerals have been applied to the shanks inboth forms of construction. These shanks are provided with seats 8, which are adapted to receive the inner ends of set or tap screws 9, which are inserted through the inner wall of the shoe, whereby to project into the recesses or openings 4 and engage the shanks 5. The heel-calks 10 may also be of the sharpened nature or form or the rectangular form 11, as seen in Fig. 8, andthese calks are provided with tapering shanks 12, which fit in the openings 3, and are provided with seats 14 to receive the set or tap screws 15, passed into the recesses from the inner wall of the shoe. \Ve preferablyinsert these set or tap screws at an incline, as by so doing the screws as tightened draw the shanks down into the openings,and they also serve to better resist any strain broughtto bear against the screws. lVe may, however, insert the screws 011 a horizontal line, as seen for screw 16 in Fig. 4 of the drawings. The recesses4 in the toe of the shoe are placed in such a position that the tap may readily be inserted from the direction of the heel end of the shoe, whereby to tap the holes for the securing-screw 9. The holes for securing the screws 15 are easily accessible to work with a short tap. By this construction it will be observed that the loosening of the screws 9 and 15 will readily permit the removal of the toe-piece and calks, whereby to insert new sharpened ones or calks and toe-pieces of the form shown in Figs. 7 and 8, requiring but a very short space of time in order to make the change and not necessitating the removal of the shoe from the hoof of the animal. \Ve preferably insert the heel-calks in position, so that the same will extend longitudinally of the shoe, while the toe-calk eX- tends transversely thereof, as seen in Fig. 1 of the drawings,and in practice we have found this desirable when d riving on slippery roads. The seats in the shanks of the calks are preferably extended across the face, whereby to insure the engagement of the screws with the shanks irrespective of whether the tap is made at any particular point to receive the screws.

While we have herein shown and described the invention in detail as it is practiced by us, yet we do not desire to confine ourselves to the specific construction, as it will be observed that various changes may be made in the de tails of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Let= ters Patent, is.

The combination with a shoe-body provided with a pair of openings at the toe end and with an opening adjacent to each of the heel ends, the said openings being square in crosssection and tapering toward their tops, of toe= pieces having shanks, the said shanks being square in cross-section and tapering toward their free ends, and being provided with recesses or seats, the said shanks adapted to be fitted into the openings in the said toe-pieces, calks having shanks fitted in the openings in the heel ends of the shoe, the said shanks being square in cross-section and tapering toward their free ends, and provided with recesses or seats, the said heel-calks extendinglongitudinally of the shoe, and set-screws inserted through the inner wall of the shoebody at an incline with their inner ends engaging in the seats of said shanks, substantially as described.

In testimony whereof we afiix our signatures in the presence of two witnesses.
